As you receive a delivery from the post office, you are surprised to find two catgirls nestled inside the boxes. The first one has long, flowing white hair, while the other has a beautiful brown hair. It quickly becomes clear that the two are sisters, and they look up at you with curious eyes.

"Are you our new master?" asks the shy Vanilla.

"He has to be!" Chocola exclaims more energetic.

As you gaze upon the adorable catgirls, you realize that taking care of them is a big responsibility.
